Having trouble with randomisation

ruby-talk

I want my program to say a diffrent maths question everytime the user
goes through the cycle, however it just does the same one :frowning: What can I
do to achive my goal?

V2 = 1 + rand(22)

V1 = 1 + rand(22)

class Die

  def roll
    1 + rand(22)
  end

end

def hello
    puts 'whats your name'
    name = gets.chomp
    puts "Hello ". + name
  end

def maths_question
  puts 'Whats the sum of ' + V2.to_s + ' and ' + V1.to_s + ' ?'
  youSAY = gets.chomp
  while youSAY != CorrectA.to_s
    puts 'Wrong, please try again'
    youSAY = gets.chomp
  end
end

def maths_congrats
  puts 'Congrats, you got ' + CorrectA.to_s + ', which was the correct
answer!'
end

hello
puts 'Do you want to do maths questions?'
domath = gets.chomp
while domath == 'yes'

CorrectA = V1.to_i + V2.to_i

maths_question
maths_congrats
puts 'Do you want to do more?'
domath = gets.chomp
end

V1 and V2 are constants calculated one time at the beginning of your
script. If you want to loop through your logic with different values
for V1 and V2 each time, you need to recompute them each time through
your loop.

When you do that, you should name them with a lower case first letter so
that ruby does not treat them as constants. Doing that will require
that you rework your logic so that you can pass in these dynamically
generated values to all of your methods that use them.
